Item Specifications for the Indiana Assessment

Grade 4 Science (Beginning 2018-19 School Year)

These item specifications serve as a foundational resource in the assessment development process. This document is the first in a series of documents that will be made available in the future.

Item specifications identify the standards being assessed. In addition they provide information about each of the related items including: evidence elicited, depth of knowledge (DOK), limits and constraints, and item types. Panels of content teachers at each grade level, representative of Indiana student populations, in partnership with the Department of Education developed the item specifications.

The 2016 Indiana Science Standards increased the breadth and scope of the 2010 standards by adding a new component: process standards. Students are expected to identify and explain content, as well as understand how the data were collected and analyzed to reach those conclusions (scientific and engineering process). The Indiana assessment is designed to test students’ understanding of science and engineering processes in conjunction with content. They are expected to integrate both into their understanding and answers.

In addition to the new content and process standards, Indiana added computer science standards to keep up with the changing technological environment our students face. These standards help prepare them to be responsible digital citizens and understand the role technology plays in modern society. Federal accountability requires that these be tested with the science content and process standards.

Overview

The rows of each item specification highlight key features of items included on Indiana assessments as follows:

Reporting Category: The broad content category for the standard representing a segment or domain of content approved by educators as key for reporting. Examples across content areas may include: Number Sense in Mathematics (7.NS); Physical Science in Science (4.PS);and Writing in English/Language Arts (9-10.W).

Standard: Each Indiana Academic Standard is noted under the Reporting Category.

Evidence Statement(s): Statements that describe the knowledge and skills that an assessment item should elicit from students.

SEPS - Science & Engineering Process Standards ER and CR Items are dual-aligned with content standards.

Standard SEPS.4 - Analyzing and interpreting data

Investigations produce data that must be analyzed in order to derive meaning. Because data patterns and trends are not always obvious, scientists and engineers use a range of tools to identify the significant features in the data. They identify sources of error in the investigations and calculate the degree of certainty in the results. Advances in science and engineering makes analysis of proposed solutions more efficient and effective. They analyze their results by continually asking themselves questions; possible questions may be, but are not limited to:“Does this make sense?” "Could my results be duplicated?" and/or “Does the design solve the problem with the given constraints?”

Evidence Statement(s)

Students demonstrate how data are analyzed in order to identify problems and solutions.

Students analyze data from tables, etc., to notice trends.

Students find a piece of data that is an outlier (way off) from the pattern.

Students make predictions/conclusions about what may have gone wrong to result in outliers.

SCIENCE 4

Sample Item:

Eric predicted that warm water would boil faster than water at room temperature. He performed an experiment to determine whether water at 40°C boiled faster than water at 20°C. The table below shows his data.

Trial Starting Temperature (°C) Amount of Water (L) Time Needed to Boil

(minutes) A 20 2 9 B 20 2 10 C 20 2 9 D 20 2 9.5 E 40 2 6 F 40 2 5 G 40 2 15 H 40 2 5.5

Part 1: Explain whether or not the data support Eric’s prediction.

Part 2: Look at the data for Trial G. Describe ONE possible explanation for why this trial has different outcome from the other trials.

Key

Part 1: A correct response is any response that indicates:

Most of the data support Eric’s prediction because the 40°C water in trials E, F, and H all took less time to boil than the 20°C water in trials A-D. However, the 40°C water in trial G took longer to boil than the water in all the other trials. Because trial G’s results are so different from the rest, this trial should be thrown out and the conclusion should be that Eric’s prediction has been proven.

Part 2: A correct response should include one or more of the following:

Trial G may be different because:

• The temperature of the stove/burner/hot plate used to heat the water sample in trial G might not have been the same as those used to heat the other samples.

• The water sample in trial G might have had something/another chemical in it in addition to the water, which made the boiling point higher for that sample than for the others.

• The original temperature of the water in trial G might have been lower than 40°C and its initial temperature recorded incorrectly in the table.

Scientists and engineers use argumentation, the process by which evidence-based conclusions and solutions are reached, to listen to, compare, and evaluate competing ideas and methods based on merits. Scientists and engineers engage in argumentation when investigating a phenomenon, testing a design solution, resolving questions about measurements, building data models, and using evidence to evaluate claims.

Scientists and engineers need to be communicating clearly and articulating the ideas and methods they generate.Critiquing and communicating ideas individually and in groups is a criticalprofessionalactivity.Communicating information and ideas can be done in multiple ways:using tables, diagrams, graphs, models, and equations, as well as, orally, in writing, and through extended discussions. Scientists and engineers employ multiple sources to obtain information that is used to evaluate the merit and validity of claims, methods, and designs.

Evidence Statement(s)

Students demonstrate how scientists and engineers use a variety of ways to communicate ideas and critique work.

Students communicate using tables/graphs. Content Limit(s)/ Constraint(s)

Sample item:

Eric predicted that warm water would boil faster than water at room temperature. He performed an experiment to determine whether water at 40°C boiled faster than water at 20°C. The table below shows his data.

Trial Starting Temperature (°C) Amount of Water (L) Time Needed to Boil

(minutes) A 20 2 9 B 20 2 10 C 20 2 9 D 20 2 9.5 E 40 2 6 F 40 2 5 G 40 2 15 H 40 2 5.5

Eric’s teacher suggests that Eric communicate his results to other scientists. Explain why it is important for scientists to communicate their results with other scientists.

Key

(A correct response is any response indicating any of the following:)

Communicating results of experiments with other scientists is important because:

• other scientists can then repeat the experiment to make sure the results are reliable

• other scientists can use the information to inform their own work on similar experiments/research

• other scientists can use the information as a basis for new research/experiments
